| Test chronology | |
The atomic bomb was a part of China's "Two Bombs, One Satellite" program. It had a yield of 22 kilotons, comparable to the Soviet Union's first nuclear bomb RDS-1 in 1949 and the American Fat Man bomb dropped on Nagasaki, Japan in 1945. With the test, China became the fifth nuclear power in the world and the first Asian nation to possess nuclear capability. This was the first of 45 successful nuclear tests China conducted between 1964 and 1996, all of which occurred at the Lop Nur test site.
